Chalk (2007)

Three rookie teachers and one unenthusiastic assistant principal face a rambunctious student body, a cantankerous set of colleagues, embarrassing rumors, equipment malfunctions and various absurdities at Harrison High, a typically provocative and volatile (although fictional) public school in Austin, Texas. The documentary-style comedy won several awards, including Outstanding Performance by an Ensemble Cast at the 2006 Los Angeles Film Festival.

Unfortunately the movie Chalk is not yet available on HBO Max.
